Rendering Odour Control

A.S.K. Piearcey Ltd were engaged by PDM (John Knights) to look at a means of improving the existing odour control at their Silvertown Facility in London.

The project was carried out in 2 stages:

Stage 1 a site visit to inspect the current system and gather the relevant design information. Which included a proposed additional test regime carried out by PDM.

Stage 2 a conceptual process design to provide a system capable of handling around 8000 m3/hr of concentrated odours which worked with the existing boiler incineration route to provide constant, seamless and reliable odour control.

The design is currently being procured for another PDM site in Nuneaton, for a larger air flow.

Our design was adapted and constructed in a very short period of time to provide an odour control safeguard in time for the London Olympics. The system was a great success, dramatically reducing the number of odour complaints, even with the additional footfall during the summer months. The design is an acid scrubber followed by a carbon adsorber (with specially impregnated, activated carbon).

The original design also included a venturi pre-scrubber for fat removal but this was not deemed necessary for the adapted design.
